Arun Sundaram joins Diane King Hall to preview this week's Amazon Prime Day event which will run for 4 days. He believes the decision to lengthen the ecommerce shopping event means Amazon (AMZN) has a large inventory ready to move. CFRA has a Strong Buy rating and a $248 price target on Amazon, highlighting the company's operating margin improvement as a key point of strength. Aside from the company's ecommerce side, Arun adds that the AWS and Advertising business segments are significant to future growth.
